This invention appertains to new and useful improvements in distributor constructions of the type used in ignition systems on internal combustion engines.

The principal object of this invention is to provide a distributor construction to insulate the contact thereof from inclement weather.

Other important objects and advantages oi the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a top plan view of the distributor.

Fig. 2 represents a vertical sectional View through the upper section construction taken substantially on line 2 2 of Fig. 1.

Fig. 3 represents a vertical sectional view taken substantially on line 3--3 of Fig. 1.

Fig. 4 represents a bottom plan View of the cap construction of the distributor.

Fig. 5 represents an enlarged fragmentary den tailed sectional viewon the high tension current contact, and connection.

Fig. 6 represents a perspective View of one of the radial contacts.

Fig. 7 represents a perspective view of the adaptor for the high tension current contact and connection.

Fig. 8 represents a cross sectional view taken substantially on line 8 8 of Fig. 5.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes the lower section of the distributor housing through which the rotor shaft 6 is journalled and which carries the rotor 7 upon which the arm 8 is located for supporting the contactor 9. Upon the contactor 9 is located the upwardly curved leaf spring 10 which is adapted to ride against the button-like contact 11 in the depending socket 12 of the conductor barrel 13, the socket 12 being connected to the barrel 13 by the narrow neck 14. This barrel 13 and socket 12 are embedded in the insulating boss 15 which rises from the annular body 16, the latter making up the cap or upper section for the distributor housing. A periphery of this body 16 is provided with a plurality of equi-distant tail-like formations 17, While extending longitudinally in the boss 15 .is `a bore 18 alined with the barrel 13 and into which the high tension current conductor 19 v(see Figs. 5) extends, so that its plug end 20 can engage into the barrel 13 to permit its spring projected detents 21-21 to engage into the internal circumferentially extending groove 22 of the barrel 13, thus interlocking the conductor 19 in electrical connection with the barrel 13.

The desired number of contact members 23 are provided and arranged circumferentially within the skirt portion 24 of the body 16. Each 60 of the ear structures 17 is provided with a cavity for receiving a socket structure 24 which are equal in number to the number of contacts 23, each of the contacts 28 being connected to a corresponding socket 25 by narrow necks 26. 65

These contacts 23 and sockets 25 are embedded in the body 16 and in the manner shown substantially in Fig. 2.

The distributing wires 27 in the various spark plugs (not shown) are each equipped with a con 70 nector such as is shown in Fig. 5 and denoted in Fig. 3 by numeral 28.

It can thus be seen that none of the connectors have their sockets disposed upwardly so as to catch water or moisture and that the contacts of the distributor are well located within the onepiece cap structure so that there is practically no likelihood of any moisture reaching the same.

While the foregoing specification sets forth the invention in speciiic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new isz- In a distributor, a dielectric cap structure, said cap structure being provided with a contact on its inner side, said body being provided with an outwardly extending enlargement at its side having an opening extending upwardly therein from the bottom thereof, and terminating at its upper end within the enlargement, an electrical connector socket in the said opening provided with r a lateral connector connecting the said socket 9 with the contact.
